TIRE-WRAPPIN G MACHINE.

' To all whom it may concern:

hasbecome an important item.

Be it known that I. FRANK M. PIERCE, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tire-Wrapping Machines; and I do hereby declare that the followin is a full, clear, and exact description oftiie same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

' In the widespread production of tires for use on automobiles and other vehicles, proper wrapping of the tire for shipment his invention relates-to a machine for rapidly applying a spiral wra per to 'a tire, gluing the same thereon an introducing a cord into the wrapping, by which the wrapper may be easily detached from the tire when so desired.

It is an object of this invention to construct a machine adapted to receive a tire supported therein in vertical position ongaged through the eye of a shuttle which carries wrapping material so that when the machine is driven the tire s caused to rotate through the eye of the shuttle and likewise the shuttle rotates through and around the tire, and a helical wrapper is thus applied upon the tire. I

It is also an object of this invention to construct a machine wherein the driving and supporting means for the tire are adjustebly mounted to position tires of different size properly with respect to the shuttle, that is,

slightly eccentric with respect thereto to give the rotating tire a. lead, resultiflgwv in the application of the paper strip' thereto without twisting of the paper.

-It is also an important obyect of this invention' to construct? a. machine adapted to .reneive tires of different size therein, and

to rotate the same synchronously with a shuttle engaged. through the eye of the tire and carrying a reel of wrepp g'material, which is led through a suitable old! do vice and around an rammes;

Application filed October 8, 1914. Serial No. 864,735.

insure flat application of the wrapping mete rial upon and around the tire which is slightly offset or eccentric for the purpose with respect to the shuttle.

degree of adjustment of the various supporting means being a different quantity, however, to insure an offset position of the tire with respect to the shuttle. V

It is furthermore an important object of this invention to construct a wrapping ma chine which operates to apply a spiral foldedstrip of wrapping materialv upon an annular object, sealing the same thereon with a. secondary peripheral strip of wrapping material and inc-losing within the wrappings a cord disposed around the, object which may be used to rip the wrappings there from. when so desired.

It is finally an. object or this invention to construct an improved wrapping machine operating efliciently and at high speed to ap 1y a wrapper to annular obpcte.

he invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. V

For this purpose a pair of bearing brackets 3, are secured on said. table 1, at one side thereof, and another pair oi similar bearing brackets 4, are mounted. war the other side thrrcof. Journaled in ti bearing brackets 3, a shaft 5, and u long Tubular member (i, having outwardly direct '"1 bracket arms Z, i pivotslly engaged u u said shaft. Journaked in. tho K.

h. A small You jo' he shaft on? i h ilw worn: and rigidly vcon to and worm gen-1' a small sprocket i if hiirh has; trained thereltllOLll a sprocket chain 20, which is in turn trained chow: u sprocket wh eel 21, connected to tho shaft of the grooved roller 8. Simi' larly the grooved roller 12, is driven from the main shaft 13, by a Worm gear 22, meshing with the worm 17, and having rigidly associated therewith a small sprocket whee] 23, which has trained thereabout and about a sprocket Wheel 24, secured to the shaft of said pulley 12, a driving chain 25. Said bracket arms 7 and 11, which support the respective grooved rollers S and 12, are con nected for simultaneousadjustment toward and away from one another, and yet in a manner to insure greater displacement of the roller 12, for a given movement of the roller 8.

For this purpose a short downwardly directed rock arm 26, is formed on the under side of said tubular member 10,'nnd is conm-c-tcd by means of a link 27, to one of the arms '7, of the swinging support for the roller 8. For the purpose of adjusting said rollers s and. 12, toward or away from one another, as the case may be, arm 28, is formed integral with the tubular member 6, on the under side thereof, and at its end has pivoted thereto an internally threaded sleeve or nut 29, which engages a load screw 30, journaled in a pivot 31, on F-Sllll table top, and actuated by a hand crank 3:3. Mounted in a bracket 33, at the rear of said table 1. is an n right stands rd 3%, which, its upper en has secured adjustah y thlzrcon a hrackct 35. A bolt 36, is th rcaded into the face of the flanged extension of said bracket 35, and journaled thereon is a disk 37. A. bracket arm 38, is secured to said disk 37, by means of stud screws 39, thus permitting a pivotal movement of said arm 38, to take lace. A small grooved roller 10, is journa ed upon a stud bolt 41, secured though the lower end of said arm 38, the length of the bracket 35, being such that said roller 40, vertically alined With said grooved rollers 8 and 12.

Another arm 12, is pivoted upon. the arm 88, and at its lower end has journaled there on a concave roller 43, Which is adapted to week upon the outer periphery of a tire 44, pieced in the machine for Wrapping. rel ati rly large heavy crescent shaped bracket to, bolted to said table top 1, and at its upper extremities has journaled thereon large and small grooved rollers 45 and 47, respectively. For this purpose the lmwer arm or extension of said crescent bracliet "i5, is stud bolt 48, provided flange 19, which coacts with a nut 48 and washer 50, to clamp said bolt at any desired position he s ut. Said roller $6, is held journaled on the stud bolt- 48, by means of a nut; 52, and a washer 53. The other smaller grooved roller 47, is journaled upon a. stud bolt 54, which is eccentric with respect to an enlarged shank portion 55, engaged through an aperture in said crescent frame and retained rigidly, though adjustably, therein by means of a nut 56 and washer 57.

a short rockslottcd,and engaged thercthrough is a with an integral A. relatively large grooved wheel 58, is so cured upon the main drive shaft 13, in the plane of rotation of said respective grooved rollers 40 and 47, and supported upon said grooved wheel: and rollers, which contact the same at three points, shuttle,.denotl .d as a whole by the reference numeral 595 A length of belt 60, is looped about said large grooved wheel 58, as clearly shown in Fig, 4, and the shuttle 59, rests thereon and is driven by the moving belt on said-rotating grooved wheel 58. Said shuttle 59, of course is provided with a flat periphery to permit the same to track in the grooves of said re spective rollers 4-6 and 47, and upon the belt 60, in the groove of the large pulley wheel 58. A hinged section. 01, is connected into, and forms a part of said annular shuttle, b means of a stud screw62, and has secure on its surface at one side, an outstanding slotted. sleeve or cylindrical member 63, the details of which are clearly shown in Figs. 18 and 19. Axially movable within said small cylinder 63, a locking. bolt. 64, which, on its outer end, is provided with a knurled head 65, and near its middle with a rigid collar 60, having an outstandin. pin 67, projecting therefrom through the s 0t in the cylinder 63. A coiled spring 68, is disposed withinsaid cylinder 03, and bears atone of its ends against said collar 66, on the lockin bolt, and at its otherend against the en wall of said cylinder, thus normally impolling said locking bolt 64, inwardly into locking position. The end of said hinged section 61, of the shuttle at which said locking bolt 04-, is disposed, is provided with a. groove 09, adapted to receive therein the tongue 70, forming a art of the main sec-. tion of said shuttle, an said bolt 64, extends through an aperture in the tongue 70, when the same is inserted into the groove of the hinged section, thus holding the hinged section locked in a closed position.

A short bracket plate 71, is bolted on one side of the tongue 70, and is provided with and having sprung t a key shaped slot therein, through which the pin 67, of the locking bolt projects. Secured on theside face of said shuttle, is a bolt 72, which has journaled thereon a paper reel comprising a disk 73, and a hub portion 74, said hub portion bein slotted longitudinally herein leaf springs 75, on diametrical oppositesides, whlch act re silientlv to retain a roll of paper upon the g H reel. Said leaf springs 75,7bearing at their ends against the stud bolt 2, act as a brake for the reel of pa or to prevent spinning or over t ravel. thereo when the machine is sud denly sto-pped. The paper-,which is denotedby the reference numeral 76, is led from the reel through a suitable tension mechanism which com rises a bracket 7 7, secured upon the face 0 the shuttle having three small said frame pins or rollers 78, 79, and 80, enga ed thereon, and around which said strip 0 paper is caused to track. From the tension mechanism the paper is led to a folder plate 81, which as clearly shown in Fig. 10, consists merely of a flat plate, one margin of which is turned over and down at an angle, so that the edge of a piece of through is caused to be olded over in a like manner. The folded strip of paper is led around a roller 82, journaled on a bolt 83, secured at an anglein the side face of the shuttle, and from said roller, which creases the fold, the paper leads to the tire upon which it is applied.

As shown in dotted lines in Fig. l, a small bracket 84, is bolted on an extension of the crescent bracket 45, and sliding vertically through slots in said bracket and down alon side of said crescent bracket extension, is a ar 85, which, at its upper end has secured thereon a small horizontal frame piece 86, in which is journaled a roller 87. The lower end of said slidablc bar 85, is connected to one'end of a long lever 88, which is pivoted in a bearing 89, upon the table 1,

aper drawn thereand at its other end is provided with a counterweight 90. Thus said roller 87, is eounterweighted to bear yieldingly upwardly beneath the tire 44.

The string 91" which is wra ped with the tire is led through an eye e ement 9-1, on iece 86, then downwardly through a tension block 92, held in place by a pin 93, from which it leads u Wardly to the tire, through an acute notch 9 ,in an end plate. 94, secured on the bracket piece 86.

A bolt 95, extends slidably through said 7 frame piece 86, and at its outer end pivotally maintains a notched cutting plate or knife 96, flat against said end plate 94, Sand "knife' being impelled against said plate by a spiral compression spring 97 For the urpose of applying and gluing a periphera strip of paper upon the tire after the spiral wrapping has been placed thereon, a small vessel 98, is bolted upon the horizontal extension 99, of an ang e'd upright 100, which is bolted to the table 1, on one side thereof, apd' 'removably journaled in saidvessel is a lnoistening roll'llll. Said vessel 98, is filled with water, and a strip of pa or 102, from'hreel 103, orted m hoo ed suplp extenslons on the outer en of the horizontal extension 99, is drawn over said moxstening roll with the adhesive side of said pa or strip contactin the same. The strip is t on drawn upwar v beneath a pin 104, and from there led neath a pin or roller 105, on a pivoted bracket" arm 106. A counterweight 107, is connected to said pivoted arm 106, and normally holds the same toward the rotating tire 44, as shown clearly in Fig.1. A drive is imparted to the main shaft 13,

by means of a ear 108, journaled thereon and adapted to be connected thereto or disconnected therefroni, as the case may he, by means of a suitable clutch 109, which is operated by a lever 110, pivoted at one end upon a standard 111, and at its other end resting upon a standard 112,-behind a stop 113. A brake is provided to stop the movement of the various mechanisms when the clutch 109, is disengaged, and for this purpose one end of a longitudinal actuating lever 114, is provided with an apertured yoke 115, adapted to be engaged to the lever 110, by means of a pin, and the other end of said lever is connected to a small bell crank 116, pivoted upon said crescent bracket 45. A brake shoe 1.17. is connected to and supported'hy a crank 118, pivoted upon the crescent bracket 45, said shoe positioned to bear downwardly upon the belt 60, on the large grooved wheel 58. A short link 119, is connected to said bell crank 116, and to the lever 118, and acts, when the lever 114, is moved by the clutch lever 110, to pull the brake. shoe downwardly upon the belt 60, thus stopping the mechanisms from movement. A small spiral spring 118, is connected to the lever 118. and to the bracket 38, and acts to normally hold the brake retrocted.

The operation is as follows:

.he tire or other annular object to be wrapped is placed into the machine by openin tie hinged section 61., of the shuttle, an d placing the article upon the grooved rollers 8 and 12, the grooved roller -10, at the upper end of the device being swung upwardly out of normal position for the purpose. The shuttle is then closed, and after holding the end of the paper strip and the string upon the tire the clutch is engaged and the shuttle rapidly rotated, driven by contact with the belt 60, confined between the shuttle and the grooved driving wheel 58. The small roller. 47, on the eccentric stud bolt can be adjusted. to hold the shuttle in proper position agaizrifi the other roller if and grooved driving wheel 58. It is to be noted particularly that the shuttle does not rotate through the eye of the annular article on a. diameter thereof, but slightly forwardly the center, and the guide roll 82, on the shuttle, is inclined, so that the folded strip of paper drawn from the reel, on the shuttle is applied fiat upon and around the tire. Of course the grooved rollera 8 and 12, may be adjusted into various ositions for articles of dili'erent size, and in View of the fact that the link 27, between said rollers, is connected at difl'erent radial distances from the point of so port thereof, the. degree of movement of sai rollers when the crank 32, is rotated is different. {Bonsaquently in all adjustments the relation of the shuttle to the article to be Wrapped is riphery thereof, the same coming from the reel 103-, around the moistening roll 101. The small concave roller 43, at the upper end of the device tracks upon said adhesive strip to insure sealing thereof upon the tire, and of course the grooved roller 40, acts to hold the tire properly positioned in the machine. string is wound with tlnatire within the wrapping, so that the wrapping may be ripped from the tire when so desired, and for this purpose the end of the string, a ball of which may be disposed at any convenient point, is led through the respective eyes 91 and 93. on the movable counterweighted frame piece for the roller 87, After the tire has been completely wrapped, the operator moves the spring impelled notched knife member 96, upwardly, thus cutting the string. All during the wrapping operation the tire is maintained in a vertical position with the shuttle also vertical and at right angles thereto rotating through the cye -ni the tire, but of course the shuttle rotates at a much higher speed than the tire. The plate 81, on the shuttle, serves to turn the edge of the wrapping strip inwardly, so that the exposed edge of the superposed layersof wrapping material on the tire is doubled, and there is slight possibility of the same being accidentally torn from the tire. The locking means for the shuttle, whereby the same is opened and closed, is exceedingl simple, the operator merely seizing the hour-led head 65, and twisting the same and the pin 67, therewith in the slotted bracket piece 71. The pin 67, of course swings through the enlarged end of the key shaped slot in said bracket piece 71, and then the knurled head 65, is pulled outwardly against the compression oithe spring 65, in the cylinder 63, the pin moving outwardly in the elongated portion of said slot in the late 71. After the looking bolt 64, has een retracted from the i'mgue 69, which interfits the hinged portion of the shuttle, the knurledhead is won a further twist, which serves to brea: the, joint between the hinged shuttle sections, due to pressure upon the slotted plate 71,

by the end of the pin. 67. The final twist described given to the knurled head serves to also osition the pin 67, in the hook shapeds 0t 120, thus retaining the locking bolt 64, retracted, and theshuttle section 61, may then be swung hack into an entirely open position by hand. To close the shuttle it is only' necessary to swing the hinged section inwardly and when the pin 67, strikes into the slot in the plate 71, it is kicked out of the hook shaped recess, thus releasing the bolt 6 which springs into locking posh tion. The leaf springs 75, associated with the reel on which the pflptll 76, is placed. serve ctlei-tually to hold the reel of paper in position as the shuttle rotates, and yet without requiring any locking mechanism for the purpose- I am aware that various details of construction may be varied through a wide range without departing from the principles of thi; invention, and l. therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
